No doubt. It can be done. From cars to dump trucks, there are many arguments to be made for "adequate" versus "comfortable". What I find slow and frustrating, based on actually having run larger saws, might not bother someone else who never knew any better.
Here's what I've found works well, from my own personal experience, without bogging or slowing my work when buried to the nose in hickory or oak:
35cc = 12"
50cc = 16"
65cc = 19"
85cc = 28"
125cc = whatever the hell you want, sprocket accordingly
Ignoring the pole saw, I've stripped my saw plan down to just three, at 35, 63, and 85cc, barred as noted above. It's a good system for hardwoods, but those who live out west and cut only softwood might choose smaller motors for the same bars.
